ELECTRODE Filed Sept. 14, 1925 CORPORATION or ILLINOISy sion 'of nimproved vaginal electrode having,

`among Nothers, the advantages below al# i' gfluded to.

An important'advantage of the instrument of our invention is that itismade to conformv to the contour ofthe vagina and thus not only .renderspossible `more e'iicient treatmentof-` i 'lo the parts ae'ote'd but isadapted to be held y y n wliichis threaded into afsocket 16 ink thefnonf'n fvinsulated portion lloffthe tipas indicated;

.properlyv in place lduring the treatments.

The invention also provides a construction adaptedtofurtheraidvinholding the instrument infplace'byineans of an angular part 15yor, fvulval groove over which thehymenal portion of the vaginav closesafterinsertlon of o,

Another and highly important feature of Athe invention is the provisionin an electrode ofthis character of a stem formed to receive n' athermometer inv amanner to provide tem- Y 3o perature readings y.at 'alltimesv during the course of the treatment,A advising thephy` sician ofthe temperature conditions of the inserted `part off the electrode and,therebyof the results being obtained.

making the effective internal tip temperature much higher than ispossible with other types of electrode which do notiinsulate the eX-ternal tissues from the heat of the electrode, and which consequentlyh-ave to be operated at temperatures lov.7 enough to accommodate thetolerance of the external tissues. The vaginal mucosa will toleratetemperatures greatly in excess of the external skin.

The curved stem 23 when attached to the electrode stem produces `adownward pull thereon that automatically elevates the uterus and bringsa sagging, sub-involutedr organ into its pro-per position, thusfacilitating treatment thereof by bringing the organ closer to theindifferent electrode 27 and prometing a greater concentration ofVcurrent thereon.

A thermometer .31 may be inserted through the cap 18 into the interiorof the tube l5 to dispose the tip 32 thereof in the socket 16 of theelectrode tip 1l, so that the temperature thereof is at all timesdeterminable. This is an important feature inasmuch as Vit is possibleto much more accurately control the eects of the treatment and to avoidoverheating and resultant burns.

W'e claim: Y

l. An electrotherapeutic device comprising an electrode including a tipinsertable in a body cavity, means for connecting said. tip in anelectric circuit, and a stem secured to said tip and adapted to bedisposed outside said body cavity When the device is in use, said stemcomprising a holloW tube of con ducting material, means for connectingthe 'same into the circuit, the inner end of'said tube being engagedWith said tip, and an insulating member in which said tube is enclosed,said tube being adapted to receive a thermometer for indicating at avisible point the temperature of the inserted tip.

2. An electrotherapeutic device, comprising an electrode including anon-insulated tip formed with a bowl to engage the cervix uteri Wheninserted in the Vagina, an insulated stem having a shoulder thereon Withwhich the vulval muscles engage by contraction thereabout to hold thedevice in place in the vagina, and `means for connecting the electrodein an electric circuit. y y
